The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections x Ni/x Sn?≈?:9, x Ni/x Sn?≈?:6 at 1073?K and along two sections x Sn/x Zn?≈?:1, x Sn/x Zn?≈?:1 at 873?K. The integral enthalpy of mixing at each temperature is described using the Redlich-Kister-Muggianu model for substitutional ternary solutions. In addition, the experimental results were compared with data calculated according to the Toop extrapolation model. The minimum integral enthalpy of approx. ?0000?J?mol-1 corresponds to the minimum in the constituent binary Ni-Sn system, the maximum of approx. 3000?J?mol-1 is equal to the maximum in the binary Sn-Zn system.
